Epic Motorsports Engine Calibration Interface (ECI)

The Epic Motorsports Engine Calibration Interface (ECI) was developed as a means to give BMW enthusiasts more control over and involvement in their BMW's engine performance. With this specially designed ECI tool, you have the ability to install the full range of Epic performance software calibrations and/or return the vehicle to its factory calibration settings. The ECI also doubles as an OBD II scanner that is capable of reading and clearing DTCs (Diagnostic Trouble Codes).

Your unique ECI tool simultaneously plugs into your vehicles OBD II port and the USB port of your PC. With the user-friendly Epic Engine Calibration Interface PC software, you can read the existing factory (or aftermarket) programming from your vehicle's ECU and email it to be upgraded to one of the various Epic Motorsports calibrations optimized for the specific vehicle. You then load the modified calibration file into the ECU using the same ECI tool.

You now have complete control of your car's engine calibration, switchable between modified or stock at will.  For customers concerned with warranty, the factory calibration can be reinstalled before a trip to the dealer, leaving absolutely no trace of tuning. After service or warranty work, you can simply reinstall your Epic Motorsports calibration.

Many Epic Motorsports calibrations include the ECI tool at no charge or $100 (correct price for your tune will be reflected at time of processing). The Epic ECI is only available when purchasing an Epic calibration, or for previous Epic calibration purchasers. The ECI loads coded Epic files only, providing an easy method to load and switch calibrations, and does not give you the ability to view and modify your own files. The Epic Motorsports ECI marries to the ECU of your car on installation, after which it cannot be used on another car.

Epic Motorsports software upgrade is for many 1996+ BMW models, including: M2, M3, M4, M5, M6, M8, 228i, 230i, M235i, M240i, 325i, 328i, 330i, 335i, 340i, 428i, 430i, 435i, 440i, 530i, 535i, and more!

Please call your BimmerWorld sales rep for more information on Epic Motorsports calibrations for your car.

For use with PC-based computers only.
